ern'orrrcarroivzomm part of Letters Patent No. 351,014, dated October 19, lacs. Application filed January 11, 1886. Serial No. 188,186: (No modeLl To all whom it. mag concern:

Be it known that I, AARON WISSLER, a citizen of the United States, residing at Brnnersville, county of Lancaster, State 'of Pennsylvania have invented a new and useful 1mprovement-in Conveyers, of which the following isaspecification. 1

This invention relates moreparticularly to the classof conveyers adapted to carry from pointtopoint grain or articles of 'a kindred nature; but it is also adapted to perform the same duty for tan, planer-chips, and'small coals. The object of the invention is to furnish a conveyer adapted to carry any suitable article delivered within its inclosure to any point in a horizontal, angular, or vertical line, and to leys, bands, or gears to drive the'same;

(lonveyers from. the earliest days of milling little'in form. Originally a wooden shaftwit-h wings pinned at an angle with its axis and set in a spiral line upon the circumference of the the grain and flour; next in use a short castiron shaft with a continuous spiral blade integral therewith; these short lengths were coupled together to form the proper length of conveyer; next a light wrought-iron shaft length with the spiral wings formed of sheetiron or sheet-steel segments hammered upon dies of the proper form, to secure the spiral blade at every point of its circuit at right angles with the shaft, the segments subsequently riveted-together, strung upon the driven at suitable points into the shaft. Occasionally plain belts have been used for the same purpose; and, finally, aplain helix of wire driven from one end. (See patcuts to Farquhar, N 0. 104,004, June 7, 1870, and Edmonson, No. 307,275, October 28, l884-grain-conveyers.) The latter devices would deliver 'grain' or matter of a similar character upon a dead-level, but would prove inoperative upon attempting to lift to any height above the same, owing to the pitch of In all the conveyers enumerated the direction.

and the connection therewith of another the conveyer would form aseries of polygonal divisions to'the curve, each separately driven; whereas with my improvement the case would be formed to the desired curvature, and the coil inserted would be driven from one point only.

My invention saves nearly all the labor con nected with either of the modes of'constr'uction described, furnishes an efiicient conveyer,

and places the manufacture of an eifective conveyer in the hands of any intelligent'mechanic, the expense of construction being not more than one-third that 01 the ordinary conveyer of the same capacity.

The drawings herewith, with the 'letters of I reference marked thereon, together with a brief explanation, will enable thosesk-illed in the art to make and use the same.

Figure 1 representsa conveyer made in accordauce with my invention, adapted to de'-- liver either in a horizontal or vertical direction, as the case may be placed- Fig. 2 is de material originally delivered by the trough G into the conveyer-case, and after filling the same the action may be made continuous by the discharge being directed into the trough,

as shown. Fig. 3 represents the driving-shaft v may indicate.

B is a wide bearing-box in connection with the case, provided with cap B and bolts B. If desired, the bearing may be divided into two parts. Cis ashaft adapted to be revolved within the same.

The conveyer is constructed of a continuous length of coiled metal wire or bar, F, according to-the nature and weight of the material to be handled and thejdistance to which the same is to be carried, and its section may be round or square. I have found, practically, that the pitch of the coil should about average the diameter of the same, asa maximum, and that or various purposes the pitch should change at quick bends, at receiving-points, and occasionally at the discharging-points. I do not therefore confine myself to any particular proportion of pitch to diameter of coil, which will be governed by circumstances of use.

.When the length of conveyer exceeds fifteen feet, one or more lengths may be coupled together in any convenient and suitable manner to make up the required length. The coils may be produced by winding upon a bar in an or-' .dir 1ary lathe, or in special spring-coiling machines.

To construct a conveyer 1n accordance with my improvement, the case is first built to the desired form of outline to adapt it to receive and deliver the material to be carried to the proper points, and the inner section of the case may be square or circular. In either case the bends should not be too abrupt,and should be .imade acurve of a radius notless than twice the diameter of the coil. I give preference to the circular section. The'coil is then cut to length and shoved into the case, following all its bends, until the discharge end is reached. The bearing box or boxes B are now secured to thecase, or near 'to the same, and the-shaft the coils, whether right or left hand in their pitch,.if arranged to deliver from the outer ends of the case, will, when the direction of their revolution is changed, draw in the material at the outer end and discharge the same at their inner or shaft-connected ends. At any desired points openings may be made in the case, the same being controlled by gates, whereby the material to be handled may be introduced within the conveyer-case, or the same may be discharged at such points.

The applicability of thisconveyer has been practically tested, and its simplicity and inexpensiveness will be apparent to an expert.

Having shown the construction, use, and advantages of my invention, I desire to secure by Letters Patent the following claims thereon:

1 As an improved article of manufacture for transportation of materials adapted thereto, a continuous bar or'wire coil of suitable metal, constructed with a differential pitch at curves in its inclosing-case, and with annifor-m pitch of coil at all other points intermediate thereto, in combination with a short driving-shaft having pulley I), and a collar, E, to which one end of said coil is secured, substantially as and for the purpose set forth.

2. As an improved article of manufacture for transportation of materials adapted thereto, a coil of suitable metal of a differential pitch at respective points, and of a uniform pitch between the same, in combination with j a case adapted to receive the same, carried from the receptive to the discharge point in an unbroken straight or curved course, or. combination of the same, whereby the arti-
